Gold Processing Plant | Multotec
What is the difference between CIP and CIL gold processing? Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution.

In March 2015, Xinhai took charge of African Zimbabwe Huangzhi 700tpd gold project, the plant is mainly quartzite gold mine, most is oxidized ore or primary ore with low sulfur ore, so Xinhai chose gravity separation + all-sliming CIL process, which achieved efficient recovery of gold, save 15% cost.
Gold CIL & CIP Gold Leaching Process Explained CCD
CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.

About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.
